BACKGROUND OF THE INVENTION Field of the Art

The disclosure relates to the field of contact center operations, andmore particularly to the field of testing for methods for textcommunication systems.

Discussion of the State of the Art

In the field of contact center operations, more centers are beginning toaccommodate additional, text-based communications commonly found in theart such as email, SMS interactions including two-factor authentication,and tertiary text messaging such as automated online messaging, tobetter serve customers who may not have access to or desire to utilize avoice connection.

There exist in the art testing methods for individual text-basedcommunications, but no system for integrated testing of all currentlyused customer-to-business text communications exists. Furthermore, whilethere are some testing systems implemented in the art currently, suchsystems require the interaction of a testing agent to operate, whichintroduces new problems such as additional expense for the time andlabor involved in testing, human error factor which may influencereliability of testing protocols, and various inconsistencies associatedwith human operation. Lastly, no automated testing method exists whichmay test interactivity and integration of these different textcommunication methods, such as responding to an SMS message with anemail or vice versa, to ensure that a business' automated communicationswith a potential customer meet or exceed requirements and expectations,including load testing to ensure that large quantities of customerqueries may be adequately responded to.

What is needed is a flexible and scalable automated testing solution fortext-based communications, that utilizes test cases to configure andexecute response and load testing of message sending and receipt, andthat produces meaningful test reports for review.

DETAILED DESCRIPTION

The inventor has conceived, and reduced to practice, in a preferredembodiment of the invention, a system and method for interactivitytesting of text-based customer communications.

In the field of contact center operations, more centers are beginning toaccommodate additional, text-based communications forms such as email,SMS interactions including two-factor authentication, and tertiary textmessaging such as automated online messaging, to better serve customerswho may not have access to or desire to utilize a voice connection. Acommon example of this would be a customer browsing through an onlinecatalog on a company's website. In such a scenario, a customer mighthave a question about a product, and may send an email to a customerservice account, allowing customers to communicate directly with agentswhile still browsing the online catalog and from the convenience oftheir computer. As well, the customer might be able to interact with anautomated help chatbot that can parse and respond to basic queries, andsome systems allow a user to send SMS messages to certain numbers foruses including product information links, callback scheduling, andtwo-factor authentication. This allows for convenient, speedy, andflexible communications, such as a customer who may be viewing an onlinecatalog from an Internet café or similar public location, where they maynot have access to a telephone or may not desire for their conversationsto be overheard by others.

Conceptual Architecture

FIG. 1 is a block diagram illustrating an exemplary system architecture100 for case-based automated email testing, according to a preferredembodiment of the invention. According to the embodiment, a case-basedemail testing system 110 may comprise a testing database 111 that storesand provides case- and test-related information such as test caseconfiguration and execution results, a case management server 112 thatcreates, stores, retrieves, and executes test cases, and that operatesan administration interface 113 that comprises an interactive interfacefor configuring and directing email test cases via a network 101, forexample from an administrator's computing device 103 such as a personalcomputer or mobile device. In this manner, an administrator mayconfigure and execute test cases remotely and may monitor the operationor results of test case execution. Test case configuration may comprisea variety of email information such as (for example) including textinformation for message fields (such as the “subject” and “body” fieldscommonly used in email messages), “to” and “from” email addresses thatmay be used to verify the operation of specific email addresses or therouting of messages to and from those addresses, specific email serverinformation such as a server to be used for sending a message or aserver to be targeted for message receipt, network information such asspecific connections, addresses, or bandwidth to be used during testcase execution, timing information such as a specific minimum or maximumtime to respond to a request or for overall execution of a test case ora “pulse” interval to determine test execution frequency and timing, orother message, system, or case-specific information. In this manner, theconfiguration and execution of a test case may be managed as preciselyas needed to adequately test the desired features or components, and maybe stored and retrieved as a complete test case for future use withouthaving to repeat configuration and without the risk of any details beinglost.

A reporting server 114 may be used to monitor test case execution andproduce reports from execution results, for example including emailmessage fields (such as sender address, recipient addresses, header,body, and other email data fields), test case execution time (forexample, tracking min/max time thresholds during test execution), whatemail systems were tested, or other data that may be useful for futurereview. Test case reports may be stored in testing database 111 andpresented for review via an administration interface 113. Email server115 may be used to send and receive email messages as directed by casemanagement server 112, and may optionally be the same email server usedin contact center operations (that is, the email server responsible forsending and receiving messages between agents and customers) or may be aseparate email server used for testing purposes, such as to test theeffects of a particular server or message configuration prior toimplementing the configuration on production systems. Plurality ofnetwork servers 116 may operate an interactive interface accessibleusing a web browser application via network 101, for example to presenttest case reports or an administration interface 113.

According to some arrangements, more than one email server may beutilized, such as (for example) to send an email message from emailserver 115 to an external email server 102 operated by a remote hostsuch as an email service provider or a private email server (forexample, operated by an administrator or other user), as well as toenable the testing of multiple email servers for redundancy, as is oftenutilized in corporate environments to prevent downtime should any singleemail server experience difficulties.

FIG. 8 is a diagram of an exemplary text-based communicationinteractivity testing system for interactivity testing of email, SMS,chats, and messaging services. An integration testing system 810 existswhich contains several components, namely an interactivity testingengine 811, a testing database 812, a plurality of network servers 813,an administrative interface 814, and a reporting server 815. Theintegration testing system 810 communicates across a plurality ofnetworks 820 with a contact center 830, which has a variety of serversfor various modes of communication, for example, an email server 831, anSMS server 832, a chat server 833, and a messaging server 834. Theparticular network of the plurality of networks 820 through which agiven communication will occur will depend on the type of communicationbeing sent (e.g., typically the Internet for email communications, acellular telephone network for SMS communications, etc.). A syntheticagent workstation manager 835 is installed at the contact center 830 toreceive and respond to communications sent by the integration testingsystem 810 to the contact center 830 through the various modes ofcommunication. Communications are either tagged by the integrationtesting system 810 for routing to the synthetic agent workstationmanager 835, or rules are set up at each of the various servers of thecontact center 830 to route messages received from the integrationtesting system 810 to the synthetic agent workstation manager 835. Thesynthetic agent workstation manager 835 operates a plurality of virtualagent workstations which are configured to receive communications of agiven type and provide context-appropriate responses, which are sentback to the integration testing system 810 for analysis. Further, insome embodiments, the synthetic agent workstation manager 835 caninitiate communications from the contact center 830 without firstreceiving communications from the integration testing system 810. Anintegration testing system 810 specifically communicates over a network820 with a contact center 830 by sending textual communications, such asemails, SMS text messages, or other forms of text messages such asonline chats or third-party messaging system formats, and listening fora response message from the contact center 830. A plurality of networkservers 813 act as interfaces between the network of the plurality ofnetworks 820 and the rest of the integration testing system 810,relaying these messages to and from an interactivity testing engine 811,which is responsible for the final creation of the outgoing messages,processing of incoming responses, and communicating with othercomponents in an integration testing system 810. A testing database 812exists in the integration testing system 810 which may be queried by aninteractivity testing engine 811 to provide templates of messages invarious forms which may be used by an interactivity testing engine 811for forming an outgoing message, or for comparison with a receivedresponse to determine if the response matches the expected template. Areporting server 815 communicates with an administrative interface 814and an interactivity testing engine 811 to receive, store, format, andpotentially analyze reports on performance by an interactivity testingengine 811, such as errors in the function of the testing engine, orwhen a received response from a contact center 830 is either delayed,missing, or not formatted appropriately compared to what the templateindicates. An administrative interface 814 communicates with both thereporting server 815 and the interactivity testing engine 811, queryingreports from a reporting server 815 to allow a user to view them, whilealso allowing a user of the interface 814 to interact with theinteractivity testing engine 811, allowing them to view the progress ofcurrent ongoing tests, manually alter tests, set new tests to begin ifnecessary, pause ongoing tests, and any other administrative task thatmay be required for the operation of the testing engine 811.

FIG. 9 is a diagram of a interactivity testing engine as used in atext-based communication interactivity testing system. An interactivitytesting engine interactivity testing engine 811 at least comprisesinternal components including an authentication tester 910, textprocessor 920, and a load tester 930. A text processor is a componentcapable of automatically interpreting communications test configurationsfrom a database, receiving any text-based communications or files, andapplying data processing techniques such as regular expressions,heuristic text analysis, and other software techniques for analyzingtextual data. An authentication tester 910 may be specially designed toanalyze any received messages for authentication codes sent intwo-factor authentication techniques, and may process suchauthentication by communicating with a plurality of network servers toaccess a web page where the authentication code must be entered, orforming a response to a communication in a form noted by a testingdatabase, and sending said communication to a contact center's textualcommunication provider. The purpose of such authentication testing is toensure that when a contact center provides a user with two-factorauthentication options, these automated authentication options functionas-expected and in a secure fashion, as reported by an authenticationtester 910. A load tester 930 is responsible for generating load-testingmessages, whether email, SMS, or some other messaging format,determining the amount and frequency of these messages to be sent to acontact center, and analyzing any results including response time,response quality, errors in responses, any associated drops in responsetime during peak load times, and associated load balancing tasks.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

FIG. 2 is a flow diagram illustrating an exemplary method 200 forcreating and saving an email test case, according to a preferredembodiment of the invention. In an initial step 201, a user may accessan administration interface 113 via their device (for example, using aweb browser on a personal computer or mobile device), and mayauthenticate in a next step 202 so they can interact as anadministrator. In a next step 203, the authenticated user may configurea new test case using plain text, facilitating an easy-to-use means fordesigning email test cases without the need for specialized training oradvanced programming knowledge. For example, administration interface113 may present a number of prompts or fields to configure specificfeatures of an email test case, such as to fill out “to” and “from”fields for messages sent during execution, or to configure monitoring orreporting settings for a reporting server 114 to track execution of thetest case. In a next case 204, the user may save the new test case andit is stored in testing database 111 for future reference, and in a nextstep 205 the saved test case may be retrieved and executed according tothe configuration (for example, if the test case is configured toexecute at a specific time or in response to a trigger such as a changein email server 115 configuration, as well as time-based executionparameters such as using response time thresholds to determine thesuccess or failure of a test step). In some arrangements, a user may beable to manually execute a test case, such as for one-time testing of aspecific feature or configuration.

FIG. 3 is a flow diagram illustrating an exemplary method 300 forcase-based email testing, according to a preferred embodiment of theinvention. In an initial step 301, a test case management server 112 mayretrieve a stored test case configuration for execution from a testingdatabase 111, for example configured synthetic email information forgenerating emails during testing, or stored testing parameters. In nextstep 302, test case management server 112 may direct a plurality ofemail servers 115 based on the loaded case configuration, for example tosend email messages with specific information or configuration, such asusing specific email addresses or servers for sending or to checkspecific email servers or addresses for receipt. In a next step 303, anemail server 115 may send a plurality of email messages according to theloaded case configuration, and operation may be monitored and logged bya reporting server 114 in a reporting step 304. In this manner, a numberof synthetic emails may be produced and sent via standard communicationchannels during testing, wherein synthetic emails are sent for normalhandling wherein they may be received at the destination, where they maythen be classified and routed according to the destination's handlingconfiguration. Synthetic emails may be routed separately from actualcustomer interaction emails, for example to be sent to synthetic agentworkstations that may then perform automated handling and responseaccording to configured test execution information. In a next step 305,an email server 115 may receive a plurality of email messages(optionally messages sent as part of a test case, or messages receivedthat were not generated by a test case, for example to test receipt-onlyfunctionality using incoming email messages), and received messages maybe provided 306 to test case management server 112 and compared againstanticipated results according to the loaded test case configuration. Forexample, if email messages are received that were sent according to atest case configuration, specific message information may be anticipatedsuch as “to” and “from” fields or text content within variousinformation fields of the message, and when a message is received it maybe compared against this predicted result to examine the execution ofthe test case and the operation of systems used during execution.Additionally, this comparison may be used to determine if a particularemail message is part of a test case, and if so which specific test caseas multiple test cases may be executed or pending during a given span oftime. Reporting server 114 may continue to monitor and log operation 304and produce a report for a test case or a system that was tested, thatmay then be stored for future reference. For example, multiple testcases with varying configurations may be executed to thoroughly test aparticular email server or network connection, and the execution ofthese test cases may be logged as a testing report on the operation ofthe system(s) in question, optionally in addition to a plurality oftesting reports for the specific test cases that were executed. In thismanner, email testing comprises an end-to-end testing operation thatcomprises each step of an email interaction from the creation of aninitial email, through each step of email routing and handling, and aresponse from the destination.

FIG. 10 is a method diagram for combined text communications testingincluding email, SMS, and messaging testing of a contact center'sautomated responses. Stored case configurations must first be retrievedif they are available 1010, from a testing database 812, by a textprocessor 920 component of a interactivity testing engine 811. Suchtesting configurations represent forms of text-based communications thatare known and able to be automatically tested with, for example specificemail or SMS forms which may be analyzed for specific contents if theirgeneral configuration is known, for processing and formulating automaticreplies to test a contact center's system 1020. In this embodiment, theinitial message to a contact center and the response from the contactcenter, are in the same form of text-based communication, either email,SMS, or some other messaging form such as online chat messages or amessaging service such as WhatsApp. After an initial message is sent toa contact center 1020, response messages may be received from thecontact center by a interactivity testing engine 811, 1040, after whicha text processor 920 compares the received response to the expectedresponse as stored in the testing database 1050, 812. Continuously aftersending an initial communication to a contact center 1020 and at everyprogressive step in the method, a reporting server 815 monitors theexecution and progress of the integration testing 1030, reporting to anadministrative interface 814 any software errors, errors in the testingitself, errors in received responses from a contact center, or evensuccessful testing results and the configurations used in such tests,for a human user to examine if necessary.

FIG. 11 is a method diagram for testing a contact center's automatedresponses using two-factor authentication. Stored case configurationsmust first be retrieved if they are available 1110, from a testingdatabase 812, by a text processor 920 component of a interactivitytesting engine 811. Such testing configurations represent forms oftext-based communications that are known and able to be automaticallytested with, for example specific email or SMS forms which may beanalyzed for specific contents if their general configuration is known,for processing and formulating automatic replies to test a contactcenter's system 1120. In this embodiment, the initial message to acontact center is in one form of text-based communication, and theresponse from the contact center is either in the same form or in adifferent form from the initial message, either email, SMS, or someother messaging form such as online chat messages or a messaging servicesuch as WhatsApp. After an initial message is sent to a contact center1120, response messages may be received from the contact center by ainteractivity testing engine 811, 1130, after which a text processor 920finds an authentication code typically sent by SMS message 1140, atwhich point the message and authentication code may be sent to anauthentication tester 910, 1140. Upon an authentication tester 910receiving a message with an authentication code for two-factorauthentication requests, it may attempt to use the authentication codein whatever manner is configured according to a testing database 812,1150, such as sending the code in a message, SMS, or email response, orsending web data to fill out an online form with the code through someAPI or POST request, attempting to automate the process of a userfilling out a form in a web-browser and submitting the code forauthentication. The authentication tester will then analyze whateverresponse is given by the contact center according to the loadedconfiguration, and report either a success or failure of the attemptedtwo-factor authentication request 1160, which may be sent to a reportingserver 815 for viewing in an administrative interface 814.

FIG. 12 is a method diagram for multi-modal text communications testingincluding email, SMS, and messaging testing of a contact center'sautomated responses, where a query and received response are ofdifferent communication formats. Stored case configurations must firstbe retrieved if they are available 1210, from a testing database 812, bya text processor 920 component of a interactivity testing engine 811.Such testing configurations represent forms of text-based communicationsthat are known and able to be automatically tested with, for examplespecific email or SMS forms which may be analyzed for specific contentsif their general configuration is known, for processing and formulatingautomatic replies to test a contact center's system 1220. In thisembodiment, the initial message to a contact center is in one form oftext-based communication, and the response from the contact center is ina different form than the initial message (for example, a contact centerreplying to an email from a simulated or real customer with an SMSresponse containing a link to a solution) may be received from thecontact center by a interactivity testing engine 811, 1240, after whicha text processor 920 compares the received response to the expectedresponse as stored in the testing database 1250, 812. According to thismethod, a link may be sent containing helpful information or a solution,or some other response to a customer, by a contact center, at whichpoint a text processor will attempt to validate the link and ensure itfollows the tested configuration of automated responses from the contactcenter 1260. It is not necessarily required that the text processoranalyze the actual contents of the link fully or even partially,provided the link merely is properly formatted and is expected in thefirst place in the tested configuration. Continuously after sending aninitial communication to a contact center 1220 and at every progressivestep in the method, a reporting server 815 monitors the execution andprogress of the integration testing 1230, reporting to an administrativeinterface 814 any software errors, errors in the testing itself, errorsin received responses from a contact center, or even successful testingresults and the configurations used in such tests, for a human user toexamine if necessary.

FIG. 13 is a method diagram for load testing of a contact center using alarge load of text communications such as email queries. A load testermay receive data from either a testing database 812 or a contact centerdirectly, regarding the contact center's text communications peak hours,and how active the communications channels are during these times 1310.A load tester 930 may then determine with a testing database 812,whether to test email capacity, SMS capacity, or some other textcommunications capacity of a contact center 1320, or it may bedetermined by a user of an administrative interface 814 manually. Thechosen form of communication, following a configuration stored in atesting database 812 which should be properly received and responded toby a contact center, may then be sent in large quantities matching orexceeding those of the center's peak hours 1330, depending on whetherthe center is being tested for current peak times or being stress testedfor volumes exceeding current peak times.
